Question

5. Would a liquid with high vapor pressure be more likely to be in liquid stationary phase or gas phase? Why? likely to be 6. When analyzing a GC spectra, you must mark a) your (b) height, and width at (e GC trace. Show your calculations either in your final report or (d) and width at (c), on the sample GC spectra below. Report the retention time of each peak (in minutes), the identity of each component in the mixture, and the percent composition of will first need to find (a)-- -' the mixture. To determine the percent composition, you b) You may assume that each component of the mixture causes the same response in the detector. Therefore, the areas under the curves can be used to calculate (e) of the mixture of compounds. (Do not include the (Dpeak in your calculations; though it did not show up here in this sample GC spectra) (g 9. You were told that your product (isopentyl acetate) eluted before your starting material (isopentyl alcohol). How can you experimentally confirm this? 8. (a) (a solid, or a liquid supported on a solid) and (c)usually the solvent or a liquid. The (d) flows through the (e) is used to separate mixtures of substances into their components. It has a (b) and carries the components of the mixture with it. Different components based on their (f) ·These components are measured by taking how far the When the solvent front () top of the plate, the plate is removed from the beaker and the position of the solvent is marked before it has a chance to evaporate. These measurements are then used to calculate the () the following equation: travelled and the distance travelled by (h) with another line , represented in R. : distance traveled by camponent distanco travcllod by solvont

Explanation / Answer

Ans 5 :

Vapor pressure is the pressure at which the gas is in equillibrium with its liquid phase.

Since the liquid has a higher vapor pressure , it will be highly volatile in nature and the normal boiling point of the compound will be low.

So in such a case the liquid will be more likely to be present in gas phase.
